I would omit any reinstall and instead use silicon pads to avoid scuffing.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

I bet those old athalon copper shims would work on these. For those who wanted to keep the IhS off. Prob have to file a little bit for clearance from some of the ICs and gold pads

May even be able to find some foam pads, make it look like a ceramic athalon/duron.

The removal of the IHS on these doesn't really help with overclocking plus the die is pretty fragile. I wouldn't want to risk using a heatsink directly on the die.

It is not hard at all to reinstall the IHS on these.

I did it back when the K6-2 chips were current and didn't have any issues reinstalling.

Whatcha think? Is this the same stuff?

Automotive RTVs are generally good sealers, but poor glues. Unless they are intended for a more adhesive role, rather than gasket sealing.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

I’m trying to find the exact stuff that amd used

I will guess that the stuff AMD used isn't silicone, or maybe it's a special heavily-modified silicone. Most silicone glues don't adhere well to metal, aluminum in particular.
It's possible that it's actually a silicone-ABS compound. Which would explain why it swells and softens with acetone, which plain silicone doesn't really do.

It's probably more similar to the stuff they install windshields with then.

It really isn't going to matter which silicone you use.

I would probably just use some of the clear stuff that Walmart sells. Pick your brand.

If you want some really awesome stuff that really seems close to the AMD stuff, go to your Honda dealer and pick up a tube of Hondabond. It is just pricier than regular silicone glue but it is also very resistant to things that will cause regular silicone to break down and/or swell up.

I’m trying to keep them as original as possible. I like unlocking them but want to put them back together as they were. For the time being I will probably leave my others as 2+ cpus. Because of collector reasons. The 570s seem like fair game though.

https://en.m.wikipedia.org/wiki/AMD_K6-III
I’ve been reading up trying to address others questions of others that may be unlockable.

Best I can tell, this particular mod is definitely a k6 2+ only mod. No regular 2 should have this ability. So best not to try.

But there are still unanswered questions.

On the non plus 3 there are two links of interest, and I am unsure of what they are for. It’s possible that moving one may actually make a k6-2/3 non plus with 128k of cache (a model that so far as I can see never existed) but this is only speculation.

So remaining questions:
-What do the two option smds on the k6-3 non plus do?
-what does the remaining smd optional position on the 2+\3+ Do?
-What do the missing smds do?
-and personally, I’d like to find out exactly the kind of adhesive used by amd so I can restore these after the mod.

Probably the same thing, since plus versions are just die-shrink. It's also possible that some K6-2 are defective K6-III with L2 disabled cache, i.e. no resistor or additional placement.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

That’s what my research was trying to determine, I don’t believe that’s the case. From what I see, all the non plus 2 cpus are cachless physically, electrically, and otherwise. It seems the only cached non plus cpus were the k6 3 cpus. What I’m saying is I don’t think there are any other models of k6 other than the 2+ that we already discovered that will have this.

You only have to look at the CPUID to know the K6-2 can never be turned into a K6-3, and the K6-3 can never be turned into a K6-3+. They don't use the same die.
